Taking votes even for something in between and getting results before you end a slide is pretty tricky unless you have properly planned. For many of us who don’t have corporate advantage of getting these numbers do have an option to use a service like Text2Vote by Sendsteps which :
- Allows you to create polls dynamically.
- Dynamically Update poll results
- Poll starts automatically as soon as you start slide show.
- Displays clear message, a template, for voters so they vote in the right way.
The service is not free but you can test out a trial to test. What prompted me writing on this service was integration with Slideshow and updation which happens behind the scenes. You need not to worry about anything , not even wirting instructions. I would say worth paying it unless you have a different corporate solution availble. Give Text2SMS try
